Abstract

This research is led to examine and explore various critical rationales and positive impacts of 7D Building Information Modeling (BIM) technology implementation in the construction industry to enhance facilities’ sustainability levels. Hence, Greenhouse Gas (GHG) emissions from buildings can be alleviated. A case study was addressed investigating a construction project of the Royal Baghdad building in Iraq. Quantity take-off evaluations using manual and numerical REVIT methods were considered. Also, 7D BIM technology was applied to predict some strategies through which the positive environmental effects of this building can be boosted. Based on those two approaches, the findings revealed that the BIM method adoption helped facilitate the quantity takeoff process of the case study and provided accurate, high-performance, reliable, and environmentally friendly means of materials estimation, eliminating massive errors (90.7% to 99.9% accuracy). Furthermore, it was found that (a) minimizing the amount of heavy fuel used in transportation, (b) using efficient fuel (like green fuel) for trucks, (c) applying facility management, and (d) clarifying the maintenance tasks and operation policies in the construction project can enhance the level of sustainability. Applying those four critical aspects can, in turn, can make this project greener and environmentally friendly.
